Abstract
On industrialized building, panels are the most important and largest quantity parts. But they have many problems. For example wooden panel's problem is "haveing many kinds of parts" and "complicated assemble". So we thought problems of industrialized panel. We looked out the object of development the planning condition. By them, we created the idea the panel is constructed by two sheets. Next, we made clear the principle of the idea, and by the principle we designned the panels, which is suited to the object and the condition. And then we developed the variety of the panel by the method of "Building Construction Method Planning".
